The ISP has told him the filter is his problem as it's classed as the customers equipment, and they have refused to take any responsibility.
If it was the ISP who called out the BT OR eng, then it the ISP that that is responsible as your contract is with them and they supplied, via a subcontractor, a faulty part.
As for it being customer's equipment, it is no diff from buying a phone handset, customer's equipment, from BT and finding it faulty when first used.
You have no contract or contact with BT OR, so no point in trying to contact them.
Anyway, you don't really need a filtered faceplate, except cosmetically. Just use a dangly filter, as I have been doing since an eng, unnecessarily called out by ISP, fitted unasked a hissy BT V1.0 filtered faceplate.
